Unlocked all clothing over the course of career mode for both male and female.

Wore all of the clothes (including colour variations) for one song each through career, solo and duet modes.

It finally popped in the clothing menu after selecting an item she had already worn but not in every colour.

This seemed a little glitchy to me but I have a theory about it.

I don't think that the game saves which items you have worn, so if you quit the game you lose all of your progress towards the achievement.

This would explain why my wife wore the entire set of clothing three times without success (quitting out to play other things etc), but on the occasion where she ran through it without stopping the achievement popped.

I would advise that once you start working towards Fashion Victim you do not quit until it gives you the achievement. Hopefully this will make it pop when each item has been worn only once.

You could also try just selecting each item of clothing one after the other without singing, as the fact that the achievement unlocked in the menu would seem to suggest that would work.

Can you please ask your wife how exactly she got the achievements for rehearsing the songs because i cant work out how to get onto another song after you finish rehearsing one?

In the rehearsal room, next to each song title is a pair of headphones with a number in them. This number shows how many times you are allowed rehearse that song. Once the numer hits zero you cannot rehearse it anymore (I think the max number of rehearsals is 2).

When you have rehearsed a song and returned to your dressing room, do not leave the dressing room to perform the song properly for the judges. Simply go back into the rehearsal room to rehearse the same/another song. Repeat this until you unlock the achievement.
